logx(3) = log10(7) (assumed the common logarithm (base 10) for "log7") x^(logx(3)) = x^(log10(7)) 3 = x^(log10(7)) log10(3) = log10(x^(log10(7))) log10(3) = log10(7)log10(x) (log10(3)/log10(7)) = log10(x) 10^(log10(3)/log10(7)) = x
That loopks like a micrometer ... 0.001 millimeter.
The natural logarithm is calculated to base e, where e is Euler's constant. For any number, x loge(x) = log10(x)/log10(e)
log(314.25e) = log10(314.25) + log10e = 2.9316

That goes beyond the capabilities of most scientific calculators, but you can calculate it with logarithms:x = 7^2011 log10(x) = log10(7^2011) log10(x) = 2011 log10(7) x = 10^(2011 log10 7) x = 10^1.699,49 x = 10^0.49 times 10^1699 x = 3.09 times 10^1699
